The federal government has been implemented several housing policies attempting to improve living quality at Eup-Myun area(rural area), but those were mostly fund supports to reconstruct or repair houses. Existing minimum housing standard is focused on urban apartments and indoor space, but the houses of Eup-Myun area are scattered and are different from urban's house space. Therefore, this study focused on these area, and intended to propose suitable minimum housing standard for Eup-Myun area. Based on literature reviews about housing standard of England, U.S., Japan and South Korea, questionnaire survey was given to 50 experts divided into 2 groups, professors of architecture and researchers on rural environment. This study proposed the direction of new minimum housing standard of Eup-Myun area, it could be added to 2 household composition, be divided into 2 groups, agricultural and non-agricultural residents into facility guideline, be added to outdoor facilities, for example warehouse and open yard, and finally be inserted water quality into environment standard. The results of this study provide insightful strategies for rural housing standard.

Purpose: Korea is expected to enter an aged society in 2018 and then a super-aged society in early 2025. The country's aging is progressing faster than any other country in the world. However, the foundation of the elderly friendly industry is weak, and measures at the government level are urgently needed. Especially, housing problems of the elderly are one of the most urgent measures to be taken. Korea does not have the minimum residential area standard for the elderly, and the current general minimum residential area standard is based on the survey of the housing situation without scientific evidence. Therefore, both standards need to be revised as soon as possible based on scientific evidence. Methods: The minimum residential area standard has been calculated following Karl H. E. Kroemer's Min or Max design also being called as-single cut and dual cut theory- as the maximum population value and minimum population value theory of Ernest J. McCormick. Therefore there is a need for a formula made using a few key factors, such as corresponding dimension, practical dimension, clearance, spare dimension, integrated dimension. These elements can be defined and used as formulas to calculate minimum residential area standards. Results: Assuming the results of the spatial variability in this study showed that it is possible to raise the standard of living in a terms of sustainable minimum size for the young, old and all residents. Implications: The government should set a minimum residential area standard with scientific grounds and set up a policy improving the life of people who live in an needy residential environment.

The size of minimum order stream has a very sensitive effect on runoff analysis model using the divergence characteristic of stream. Therefore, in this study, the threshold area of minimum order stream has been examined the change characteristic of topographical parameters. The subject basin of the research was the upper basin of the Kumho water gage station which is located in the middle of the Kumho river. The 1:25,000 numerical geography which was constructed $10{\times}10m$ mesh was used. The range of investigation of topographical parameters are number of stream order, length, area, slope, basin relief, sinuosity ratio, drainage density and total stream length etc. It was found from the result of analysis that the threshold value of minimum order stream has a very big effect on topographical parameters of basin. It was found that the threshold area of minimum ord er stream revealed under $0.10km^{2}.$ Furthermore, the parameters showed a serious change except for over $0.10km^{2}.$

단일 조사구에 의한 삼림군집구조 조사시 교목층의 적정 조사구면적을 결정하기 위하여 신갈나무, 졸참나무, 소나무, 굴참나무 등이 혼효하고 있는 덕유산지역 혼효림군집의 교목층을 대상으로 nested design에 의하여 19개의 조사구를 설치한 후 종수-면적 곡선, performance curve등을 적용하였다. 종수-면적 곡선에 있어서 조사구면적의 증가율보다 출현종수의 증가율이 낮은 최소 조사구 면적은 500$m^2$이었으며, 조사구 면적의 증가율에 비하여 출현종수의 증가율이 1/2이하인 최소 조사구 면적은 1,000$m^2$이었다. Performance curve를 작성한 결과 조사구 면적 900$m^2$ 이상에서 주요 수종의 중요치가 일정한 경향으로 구분되었으며, 조사구 면적 500$m^2$에 인접한 소나무 대 경목을 제외할 경우 조사구 면적 500$m^2$ 이상에서 일정한 경향으로 구분될 것으로 추정되었다. 종다양도는 조사구 면적 400$m^2$ 이상에서 큰 차이를 보이지 않았다. 전체 조사구 면적에 대한 유사도지수는 조사구 면적 900$m^2$, 400$m^2$ 이상에서 각각 90, 85% 이상의 값을 보였다. 이상의 결과와 본 조사지의 경우 혼효율이 비교적 높은 삼림군집임을 고려할 때 삼림군집구조 조사를 위한 단일 조사구의 면적은 일반적인 경우 500$m^2$, 보다 정확성을 요구할 경우 대체로 1,000$m^2$가 적정 최소 면적이라고 할 수 있었다.

The minimum temperatures are important element in the daily human life, the climatic classification, and so on. In this study, the authors aim to make an analysis the distribution characteristics of minimum temperatures of 95 weather stations in Korea by using the Climatological Standard Normals of Korea VolumeI, VolumeII, and the Climatological Standard Normals of North Korea. The important results are as follows 1) The daily, fifthly, and tenthly minimum temperatures show the highest rate of occurrance on 14th of January( Occurrance rate : 56.6% ), 16~20th of January( 37.6% ), and the middle ten days of January( 82.1% ) respectively. 2) In the regional distribution of minimum temperatures in winter, the values of northern part, inland area, and west coastal region are lower than those of southern, coastal, and east coastal regions respectively. And, bigger cities and industrial area( Seoul, Incheon, Daejeon, Daegu, etc. ) have larger values than the its vicinities. 3) When the daily minimum temperature is $0^{\circ}C$ and less, the days of northern part, inland area, and wests coastal region are higher than those of southern, coastal, and east coastal regions respectively.

In this paper, a high-temperature superconductor(HTS) current lead operating in current sharing mode is described. The minimum heat dissipation and the optimum safety factor(cross-sectional area) is obtained analytically for partial current sharing HTS leads. It is assumed that the current lead is in conduction cooled state, and the sheath material is the alloy of silver and gold. The reduced cross-sectional area results partial current sharing state, and consequently reduces conduction heat transfer, but the Joule heat generation is increased. The optimized HTS current lead is different from the conventional copper leads. In the copper leads, the minimum heat dissipation is obtained for the zero gradient of temperature at warm end. However, the temperature gradient at warm end is not zero when the HTS lead operates at minimum dissipation state.

In optimum design of packaging container for bulk materials, minimum board area, compression performance and distribution efficiency must be considered. In this study, mathematical models for minimum board area (RMA), compression strength (CS) and maximum compression strength per unit board area (MCSA) of container as algorithm for optimum design of packaging conatiner for bulk materials were developed as follows : RMA=f(V,D), ${\alpha}_{RMA}=f(V,D)$, MCSA=f(V,D), and ${\alpha}_{MCSA}=f(V,D)$. In order to develop these models, compression test according to various dimensions of container and response surface analysis for minimum board area, compression strength, and maximum compression strength per unit board area of container were carried out. In developed models, volume and depth of container were principal independent variables. Through the verified results for these models, optimum design of packaging container on the design conditions and limit conditions was possible. These models might be used in developing optimum design software of packaging container for bulk materials.

The purpose of the study is to establish the concept of residential standard, and at the same time to investigate the area of the minimum residential standard in the countries of the world through the preceding studies. In addition, it also aims at establishing the objective residential standard by comparing the residential standard of Korea with that of foreign countries, examining the problems and finding out the matters to be improved through the comparison of the residential standard in advanced countries with the minimum residential standard of Korea. The standard residential area, derived from the process of examining the minimum residential standard, will be used as the basic material for the calculation of the reasonable area in the surface plan for the study of low-cost housing development. The method of the study is to establish the concept of residential standard and at the same time to find out the problems in the minimum residential standard of Korea and improvement methods through the comparison of the residential standards in other countries. As the result of the studies focused on the area among the residential standards, it is found out that the Korea's residential area per capita is established as the least in comparison with that of advanced countries. The real area decided depending on the size of social space suitable for living can play a role in improving the degree of satisfaction in the person's living in the residential area. Therefore, it is urgently necessary to make a depth study on the surface area of the minimum residential standard, and it is also required to propose the residential standard and directions for the improvement of the qualitative level rather the quantitative expansion of residential structures.

Providing an adequate housing to the socially underprivileged with a weak economic base is the most difficult task of housing policies. Korea established minimum housing standards and has used them for housing policies. However, the level of Korean minimum housing standards is far lower than that of foreign minimum housing standards. Thus, this study made a comparative analysis of Korean minimum housing standards with foreign housing standards in various aspects in order to guarantee housing quality of the socially underprivileged in Korea. In particular, the floor area and ratio of small lease homes are minutely examined to present the actual housing standard of the socially underprivileged. The level of Korean minimum housing standards suggested in this paper is very close to that of Japanese minimum housing standard, which is 37.95 $m^2$ for a 3 member family and just above Chombard de Lauw's pathological limit (36.03 $m^2$). As this research is specifically focused on the establishment of minimum floor area standards for the socially underprivileged, further research should be made in consideration of more specific requirements of various groups for the socially underprivileged.

본 연구에서는 실제 대형 상수관망에서 보다 효율적이면서도 정확한 신뢰도를 추정할 수 있는 segment를 기반으로 한 minimum cutset 방법을 제안하였다. 기존의 상수관망에서 minimum outset을 기반으로 한 모형은 상수관을 minimum outset의 최소단위로 다루어 상수관 파괴에 따른 피해영역을 과소산정할 수 있는 문제점을 가지고 있다. 그러나 제안된 신뢰도 추정 모형은 기존 신뢰도 추정 모형과 달리, 상수관 파괴에 따른 피해영역을 현실적으로 추정하기 위하여 segment와 unintended isolation, 그리고 수리학적 피해인 압력저하영역을 도입하였다. 또한 minimum cutset 방법에서 정의될 수 있는 minimum cutset을 상수관망 내 일부 절점의 비정상 상태를 야기하는 segment 1개로 정의하였으며 정의된 minimum outset의 동시파괴조합의 확률을 고려하기 위하여 success mode approach를 적용하였다. 제안된 모형은 제수밸브의 위치와 수를 고려하여 상수관 파괴에 따른 피해영역을 추정하며, 실제 대형 상수관망인 Chester Water Authority에 적용한 결과, 기존 신뢰도 추정 모형과 비교할 때 보다 실제적인 피해영역의 추정과 이에 따른 신뢰도의 추정이 가능하였다.
